This paper presents a robust hybrid improved dolphin echolocation and ant colony Horse Vice Prevention optimization algorithm (IDEACO) for optimizing the truss structures with discrete sizing variables.The dolphin echolocation (DE) is inspired by the navigation and hunting behavior of dolphins.An improved version of dolphin echolocation (IDE), as t
ABSTRACT:This paper presents a review of the techniques used to reduce aerodynamic drag over bluff bodies such as cylinders, spheres, 2D bodies with blunt backs and their application to commercial road vehicles.The recent research carried out on the drag reduction is presented and categorised.A new classification of the techniques is introduced and
Disk Our understanding of how the host immune system thwarts bacterial evasive mechanisms remains incomplete.Here, we show that host protease neutrophil elastase acts on Acinetobacter baumannii and Pseudomonas aeruginosa to destroy factors that prevent serum-associated, complement-directed killing.The protease activity also enhances bacterial susce
This paper presents a review of concepts related to wildfire risk assessment, including the determination of fire ignition and propagation (fire danger), the extent to which fire may spatially overlap with valued assets (exposure), and the potential losses and resilience to those losses (vulnerability).This is followed by a brief discussion of how
Double parton distribution functions (dPDF) represent a tool to explore the 3D proton structure.They can be measured in high energy proton-proton and proton nucleus collisions and encode information on how partons inside a proton are correlated among each other.dPFDs are long sleeve tee studied here in the valence quark region, by means of a consti
